Chelsea boss Thomas Tuchel admits Reece James has suffered an injury setback.

James looks set to miss Thursday's Premier League clash with Norwich after suffering a new injury setback.

The England defender only recently returned from a two-month layoff with a hamstring tear, enjoying a starring role and scoring the opener in Saturday's 4-0 demolition of Burnley at Turf Moor.

However, James is a big doubt for tomorrow night's trip to Carrow Road after sustaining a new muscle injury on the opposite leg, with manager Thomas Tuchel admitting his concern.

“We are worried," the German told reporters on Wednesday. “It's not good news. It's a setback for sure, we hope it's not a bad one."
